BOULDER, Colo. (AP) -- A woman who claims to see similarities between her own sexual abuse as a child and the case of JonBenet Ramsey has a history of making false reports, California officials said in Sunday's Daily Camera.

The Boulder newspaper reported last week that the California woman suggested the 6-year-old beauty queen was killed accidentally when an asphyxiation technique was used by an adult to stimulate orgasmic response.

Sheriff's investigators in California spent hundreds of hours looking into the woman's claim in 1991 that she had been raped. They were unable to confirm her claim, the paper said.

``She has filed a number of reports with us and most of them have been determined to be unfounded,'' said San Louis Obispo County sheriff's Sgt. C.J. Bell.

The 37-year-old woman has drawn parallels between her experiences and the physical evidence of garroting found on JonBenet's body, the newspaper stated.

Boulder County District Attorney Alex Hunter initially described the information as new evidence that needed to be thoroughly investigated. No one answered the telephone at his office Sunday.

JonBenet was found beaten and strangled in the basement of her family's home on Dec. 26, 1996. The coroner also found signs of injuries in her genital area.

A grand jury investigated the case for 13 months, but no charges were filed. Police have said JonBenet's parents remain suspects. The Ramseys, who have moved to the Atlanta area, deny any involvement in her death.
